Build a Better Trailer Brake and Light Tester with Wireless Control!

This trailer brake and light tester was inspired by @Scottthesigncrafter and the video he created for a similar build. After servicing my bearings, I realized testing the brakes would be difficult without some controller that was preferably wireless, and this build worked flawlessly for my needs. All parts are available from amazon.com, and the list follows: Nanuk 920 Case https://a.co/d/2ywvQKy 4-Way Fuse Block https://a.co/d/9AVzSEn Ground Terminal Bar https://a.co/d/5YTcLpm LED Flasher https://a.co/d/gspg7QW Timer Relay https://a.co/d/iaCMGTU 20 Amp Fuses https://a.co/d/eHZQMtD 7-Way tester https://a.co/d/eHZQMtD 24v to 12v Converter https://a.co/d/3CrQg1A 12v wireless Relay https://a.co/d/9YMPY4F Makita 18v Adapter https://a.co/d/hv5YL2I 7-Way Wire Adapter https://a.co/d/ea5PxK8
